Description

Lamp structure capable of keeping luminous rate

Technical Field

The utility model relates to a lamps and lanterns, concretely relates to keep luminous efficiency's lamps and lanterns.

Background

Waterproof lamps and lanterns are the full leakproofness structure usually, and through the luminous heat that produces of bulb light source, because the bulb temperature ratio is concentrated, adopt the fan heat dissipation to the fan forms air cycle in inside, and derive outside heat dissipation through the radiator. However, the temperature of the working environment inside the lamp is still relatively high, and various grease and smoke can be generated by inevitable internal parts due to high temperature. Because the inside is the full leakproofness structure, the inside granule such as dust that can contain simultaneously of lamp body, under this complex situation, various dust, grease and smog are attached to bulb and lens surface easily to arouse that bulb luminous efficacy reduces and the life-span of bulb shortens, takes place to explode the bubble phenomenon even.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a lamp structure for keeping the luminous rate in order to solve the problem that the existing waterproof lamp has the aforesaid problem.

A lamp structure capable of keeping luminous efficiency comprises a shell, a light source, a fan, a first lens and a second lens, wherein inner cavities for processing air are reserved on two sides of the first lens in the shell, a negative ion generator is arranged in each inner cavity, and the negative ion generator is arranged at one side of the first lens.

Furthermore, the first lens is arranged on a projection path of the light source in the shell through a bracket, and the negative ion generator is arranged on the bracket.

Furthermore, the negative ion generator comprises a carbon fiber brush, and the carbon fiber brush is positioned between the first lens and the second lens.

Furthermore, a circulating air duct is arranged in the shell, and the fan is arranged on the circulating air duct.

Furthermore, the circulating air duct is a passageway for circulating air up and down in the shell.

Furthermore, the circulating air duct is provided with an adsorption material.

Furthermore, the adsorbing material is positioned at one end of an air inlet of the fan.

The utility model has the advantages that:

1. the utility model discloses an anion generator produces the anion of taking the negative charge in with the lamp body and floats in the casing in the air dust, grease and the smog dust of taking the positive charge carry out the electrode neutralization, make its natural deposition, and can not depend on light source and lens surface, enable from this that the light source keeps good luminous efficiency and increase of service life.

2. The utility model discloses an anion generator is located a side position of first lens, and the carbon fiber brush is located between first lens and the second lens, from this, can prevent effectively that anion generator from touching with other parts, better realization ground connection or static clearance design, the performance of effectual improvement product simultaneously.

3. The utility model discloses still be equipped with adsorption material, can effectual absorption inside dust, grease and smog dust after anion generator handles, make the interior ability of casing keep good air circumstance, the performance of better improvement product.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, the lamp structure for maintaining the luminous efficiency includes a housing 1, a light source 2, a fan 3, a first lens 4 and a second lens 5, an inner cavity 12 for processing air is reserved on two sides of the first lens 4 in the housing 1, an anion generator 6 is arranged in the inner cavity 12, and the anion generator 6 is mounted at one side position of the first lens 4.

In one embodiment, the negative ion generator 6 includes a carbon fiber brush 61, and the carbon fiber brush 61 is located between the first lens 4 and the second lens 5. The first lens 4 is arranged on the projection path of the light source 2 in the shell 1 through a bracket 7, and the negative ion generator 6 is arranged on the bracket 7. The air-conditioning unit is characterized in that a circulating air duct 11 is arranged in the shell 1, the fan 3 is arranged on the circulating air duct 11, and the circulating air duct 11 is a passage for circulating air up and down in the shell 1. In order to improve the air quality in the casing 1, the circulating air duct 11 is provided with an adsorbing material, and the adsorbing material is positioned at one end of the air inlet of the fan 3.

The utility model discloses during the application, utilize anion generator 6's theory of operation, with the various dusts that produce in the lamps and lanterns, grease and smog adsorb specific place, like keeping away from the region of light source 2 and optical device (like first lens 4), thereby prevent that it from depending on and arousing other bad consequences at light source 2 and optical device (like first lens 4 and second lens 5) surface, thereby anion generator 6 installs the position on one side at the first lens 4 of inner chamber 12, with light source 2, first lens 4 and second lens 5 have a certain distance, make anion generator 6 carry out purification treatment with the air better on inner chamber 12. The negative ion generator 6 attaches negative ions to air particles, increases mass and single electric property, enables the negative ions to be deposited at a set position (such as a relatively closed position where no flowing air flow passes) or to be adsorbed and filtered by an adsorbing material, and can select negative ion generators with different release strengths according to the size of the working space in the lamp.

The negative ion generator 6 generates negative ions by using a method of boosting the power frequency voltage to the required voltage by using a high-voltage transformer, and releases the negative ions into the surrounding air to purify the air. The negative ions are generated by raising low voltage to DC negative high voltage by pulse and oscillator through the negative ion generator, and generating high corona by using the DC high voltage at the tip of the carbon fiber brush 61, so that a large amount of electrons (e-) are emitted at high speed, and the electrons can not exist in the air for a long time (the service life of the existing electrons is only nS level), and can be immediately absorbed by oxygen molecules (O) in the air₂) And capturing to form negative ions for purifying the air in the lamp body.
