Abstract
The utility model relates to a lamp with R7S lamp holders, in particular to an LED lamp with R7S lamp holders, belonging to the field of lamps. The lamp with R7S lamp holders comprises a base (1) and R7S lamp holders (2) arranged at the two ends of the base. A radiating shell (3) is installed on the base. A circuit board (4) is arranged on the panel of the radiating shell. At least one light emitting diode (5) is installed on the circuit board (4). A light emitting diode driving device is arranged in the base (1) and is respectively and electrically connected with the R7S lamp holders (2) and the circuit board (4). Since the light emitting diode (LED) is adopted, the power is small from 0.06 watts to tens of watts at most, the luminous efficiency is high, the temperature is low and the lamp is an energy-saving environment-friendly product. Since the LED is used to substitute for the straight tube type halogen tungsten lamp, the energy is saved, the environment is protected and the lamp design requirements on the temperature are greatly reduced.
Description
Technical field
The utility model relates to light fixture, more particularly, relates to the LED light fixture of band R7S lamp holder.
Background technology
The present bulb that has standard R7S lamp holder is the straight pipe type halogen tungsten lamp, and full-length is 78mm, 118mm, 189mm and 254mm, and power is 50 watts to 2000 watts.This bulb power is big, and luminous efficiency is low, and temperature is very high, causes electricity charge waste serious, and because the temperature height causes the designing requirement of corresponding light fixture than general bulb height.
Summary of the invention
The LED light fixture that is provided with the R7S lamp holder that provides a kind of luminous efficiency high is provided the purpose of this utility model.
The utility model is that the technical scheme that is adopted that achieves the above object is: a kind of light fixture of the R7S of being provided with lamp holder comprises base, the R7S lamp holder that is provided with at the base two ends; Radiating shell is installed on base, on the plate face of radiating shell circuit board is set, at least 1 above light emitting diode is installed on the circuit board, light emitting diode drive device is set in base, light emitting diode drive device is electrically connected with R7S lamp holder and circuit board respectively.
The utility model adopts light emitting diode (LED) power little, from 0.06 watt to maximum tens watts, and the luminous efficiency height, temperature is low, is the energy-conserving and environment-protective products.Replace the straight pipe type halogen tungsten lamp with light emitting diode (LED), both energy-conservation, environmental protection again, in the time of can also reducing design lamps greatly simultaneously to the consideration of temperature.
Description of drawings
Fig. 1 is the exploded view of the utility model preferred embodiment;
Fig. 2 is the outline drawing of the utility model preferred embodiment.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
