Abstract
The invention relates to an automobile lamp, which comprises a lamp shell, a lampshade and a luminous module, wherein the luminous module is arranged in the lampshade, and comprises a constant-current power supply and a luminous plate; the luminous plate comprises an aluminum-based circuit board and patch type light-emitting diode chips arranged on the aluminum-based circuit board; and the light-emitting diode chips are uniformly distributed on the aluminum-based circuit board. The automobile lamp disclosed by the invention has high brightness, high thermal diffusivity and long service life.
Description
Technical field
The present invention relates to light fixture, particularly a kind of light fixture that is used for automotive lighting.
Background technology
Along with the progress of society, automobile is more and more important for people's life, and the people's activities scope also enlarges thereupon; Usually need drive at night; Some remains the bulb of traditional high brightness the car light of existing automobile, and this bulb luminous intensity is bigger, but heat radiation is more serious; And the service life of bulb is shorter, needs periodic replacement.Also use the light emitting source of LED light emitting diode in some automobile lamp as automobile lamp; But LED diode caloric value also is bigger; And mainly receive the influence of LED caloric value the service life of LED diode; Therefore, the automobile lamp of existing LED diode is still limited service life.
Summary of the invention
The objective of the invention is to short problem in service life, a kind of automobile lamp that can address this problem is provided to the existing automobile lamp existence described in the background technology.
Realize that goal of the invention technical scheme of the present invention is following:
A kind of automobile lamp; It comprises lamp housing, lampshade, is arranged at the light emitting module in the lampshade; Described light emitting module comprises constant-current supply and luminous plaque; Luminous plaque comprises aluminum-based circuit board and is arranged at the paster type light emitting type chip on the aluminum-based circuit board, and described aluminum-based circuit board is an arc surface, light-emitting diode chip for backlight unit evenly distribute with aluminum-based circuit board on.
Described lampshade is the lampshade of PC material.
Described lamp housing is the lamp housing of aluminium alloy.
Described aluminum-based circuit board is a concaved circular cambered surface.
Beneficial effect of the present invention comprises aluminum-based circuit board and is arranged at the paster type light emitting type chip on the aluminum-based circuit board for the luminous plaque because of automobile lamp of the present invention; The heat that SMD diode chip for backlight unit sends is delivered on the lamp housing through aluminum-based circuit board; Can play good cooling protection effect to the paster type light emitting type chip; Therefore, can prolong the service life of paster type light emitting type chip.Because aluminum-based circuit board of the present invention is an arc surface, therefore, the light that the paster type light emitting type chip sends has concentrated illumination zone; Because lamp housing is an aluminum alloy material, therefore, heat dispersion is better; Because lampshade is the lampshade of PC material; Therefore cost is low, and transparency is high, can strengthen illuminating effect.
Description of drawings
Fig. 1 is a sketch map of the present invention;
Among the figure, 1 is lamp housing, and 2 is lampshade, and 3 is power supply, and 4 is aluminum-based circuit board, and 5 is the paster type light emitting type chip.
The specific embodiment
With reference to a kind of automobile lamp shown in Figure 1; It comprises lamp housing 1, lampshade 2, is arranged at the light emitting module in the lampshade 2; Described light emitting module comprises constant-current supply 3 and luminous plaque; Luminous plaque comprises aluminum-based circuit board 4 and a SMD luminous utmost point die 5 described aluminum-based circuit board 4 done on the aluminum-based circuit board 4 is set for arc surface, light-emitting diode chip for backlight unit evenly distribute with aluminum-based circuit board 4 on; Described lampshade 2 is the lampshade 2 of PC material; Described lamp housing 1 is the lamp housing 1 of aluminium alloy; Described aluminum-based circuit board 4 is a concaved circular cambered surface.Because the luminous plaque of automobile lamp of the present invention comprises aluminum-based circuit board 4 and is arranged at the paster type light emitting type chip 5 on the aluminum-based circuit board 4; The heat that SMD diode chip for backlight unit sends is delivered on the lamp housing 1 through aluminum-based circuit board 4; Can play good cooling protection effect to paster type light emitting type chip 5; Therefore, can prolong the service life of paster type light emitting type chip 5.Because aluminum-based circuit board 4 of the present invention is an arc surface, therefore, the light that paster type light emitting type chip 5 sends has concentrated illumination zone; Because lamp housing 1 is an aluminum alloy material, therefore, heat dispersion is better; Because lampshade 2 is the lampshade 2 of PC material; Therefore cost is low, and transparency is high, can strengthen illuminating effect.
